DRYING AND HEATING APPLIANCE FOR LAUNDRIES, 80C.

SPECIFICATION forming part of Letters Patent No. 631,061, dated August15, 1899.

Application filed September 6, 1898. Serial No. 690,343. (No model.)

To all 1.0700711 it nuty concern:

Be itknown that I, CHARLES C. BARBOUR, a citizen of the United States,residing at Grand Rapids, in the county of Kent and State of Michigan,have invented certain new and useful Improvements in Drying and HeatingAppliances for Laundries, VarnishRooms, &c., of which the following is aspecification.

My invention relates to improvements in heating and drying applianceswherein the circulation of air is induced by a rotary fan and thecirculating air is heated by passing between and around the pipes of asteam-coil; and its object is to extract as far as possible all foreignmatteras dust, &c.from the air before it reaches the drying-roo1n. Iattain this object by the mechanism illustrated in the accompanyingdrawings, in which Figure 1 is a longitudinal section of the airchamberand its several adjuncts on the line as x of Fig. 2. Fig. 2 is a plan ofthe same on the line 11 y of Fig. 1, and Fig. 3 is a sectional elevationof a modified form of airchamber.

Similar letters refer to similar partsthro ughout the several views.

In the construction of my drier Imake an air-chamber B, having placed inits open end a rotary fan A in position to force air swiftly into andthrough the air-chamber. At the back end of the air-chamber I form areturn curved wall F and just back of the fan I form anupwardly-inclined slide or deflector E, that causes the inflowing air toglance upward, so that it will more readily follow the curve of the backwall of the air-chamber.

At the base of the curved back wall and between it and the deflector Iplace a pan G, designed to be filled with water, preferably flowingthrough, in position so that the current of air upon leaving the curvedback will come directly in contact with the surface of the water, sothat any dust that may be in the air is likely to be absorbed by thewater, and thus prevented from passing into the dryingroom D. Really butone surface, so to speak, of the current of air comes in contact withthe water, and to avert the danger of any dust escaping to thedrying-room I place a second pan G, which is considerably longer thanthe first, immediately below the first, so that a thin passage-way Hisformed between them for the current of air. This pan, like the first, isfilled with water, so the current of air in passing around the upper panand under the deflector must pass over and in contact with the surfaceof this pan of water, thus submitting the current of air to a secondcleansing. The passage of the air over the upper pan causes a fine sprayof water from its surface to flow over its edge into the lower pan, asindicated at g, (which, in fact, is the source of supply to the lowerpan,) and thus forms a thin wall of dripping water, through which thecurrent of air must pass, between the pans to pass through thepassage-way H. After leaving the water the current of air passes through,between, and around the pipes of the steam-coil O, and thence intothe drying-room D virtually clear from dust, at very necessary conditionwhen drying varnishes or even when used for laundry drying.

In cases where the cleansing of the air is not so necessary a single panof water may be used, either by dispensing with the lower pan in Fig. 1or by the modified form shown in Fig. 3, where the current of air isdirect, or virtually so.

The supply of water for the upper pan, where two pans are used, maybebya steady flow through water-pipes or by any other convenient means.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is-

In an appliance for purifying air for drying purposes, a rotary fan, anupwardly-inclined chute back of said fan, an air-chamber and areturn-chute back of said incline, a shallow water-tank at the base ofsaid return-chute and in the line of the air-current therefrom, a secondwater-tank below said shallow tank in position to receive the drippingsfrom said tank and to form a thin air-chute between the tanks for thepassage of air through the spray to the heating apparatus and to thedrying-room, substantially as and for the purpose set forth.

Signed at Grand Rapids, tember 2, 1898.

CHARLES C. BARBOUR.
